AUCKLAND, New Zealand — Canadian teen Bianca Andreescu has recorded her second stunning tennis upset in as many days.

The 18-year-old from Mississauga, Ont., downed the legendary Venus Williams 6-7 (1), 6-1, 6-3 in a quarterfinal on Friday at the ASB Classic.

Ranked No. 152 in the world, Andreescu beat the third-ranked and former world No. 1 Carolina Wozniacki on Thursday before taking out No. 38 Williams, a seven-time Grand Slam champion and a former world No. 1.

Andreescu won 11 straight games against Williams after losing the first set and falling behind 1-0 in the second set.

“I believe that anything is possible and tonight I think I did the impossible,” Andreescu said in an on-court interview after the match. “I don’t even know what to say. It’s just such an amazing feeling.”

Meanwhile, Germany’s Julia Goerges came back from a set down on Friday to beat Eugenie Bouchard of Westmount, Que., for a spot in the tournament semifinals.
